Rea is scheduled to throw 3-to-4 innings for Triple-A El Paso on Sunday, Dennis Lin of the San Diego Union-Tribune reports.
Manager Andy Green says Rea will make at least one or two of these abbreviated starts as part of tapering his workload for the overall season. This is simply a precautionary appearance for the young pitcher, who will likely return to the majors in short order. Rea has already eclipsed 50 innings this season, a number the Padres don't seem inclined to push.
